gpx files from twonav app include hr and cad

Recently, my twonav app (smartphone) started crashing frequently. Inspecting the gpx files I observed that these files include heart rate and cadence for each trackpoint. But I have no heart rate receiver nor any cadence device in my bike. Is it possible that both facts are related (crashing and strange data in gpx file)??

Yes it is strange that you get sensor data in a recorded GPX file. It should not cause a crash, but have you tried to record in TRK format? Have you tried to reset Default configuration? (Menu > Settings > System > Device).
